I struggled a bit before giving them the 5th star but in the end I felt it was fair. I struggled because this isn't a normal BnB, this is an apartment within a hotel and I kept forgetting I was staying at an Airbnb not a hotel. I have different expectations of an Airbnb host than I do for a hotel. As an example, thrice weekly cleaning is included (something I've never had at an Airbnb) and I was out of toilet paper. I asked the maid for a roll and she smiled (it's Thailand) and said sorry, I cannot. I was really angry for a few minuted until I remembered I wasn't staying in a hotel, I had paid for an Airbnb. In every Airbnb I've ever stayed in there was toilet paper when I arrived but if I ran out during the stay I didn't contact the host I went to a market and bought some. Same for everything else. That's what I mean you have to remember it's an Airbnb because it feels like a hotel. It's SPOTLESSLY clean, the cleanest Airbnb I have ever stayed it. The staff is unfailingly friendly and polite and eager to help, to the point that the night guard will walk over and push the elevator button when you come in so that it's on the first floor when you get to it. It's super quiet, I don't think I ever heard any outside noise. The bed was great, the linens obviously expensive, I asked for a couple extra pillows (helps with a back issue) and they were supplied. The bathroom was a little small but adequate for the task. It had a walk in shower which is my preference over a tub.
I upgraded to a small apartment from the room that I originally booked which shows on this site and I'm glad I did for the space (still small, but bigger). It had a small sitting area and a kitchenette (full sized fridge, counter, sink, microwave) but no stove top. If you want to cook more than boil stuff this might not be your place. I cook, but I rarely cook in Thailand because food is abundant, cheap, and available 24 hours. If you walk out of the hotel at noon you are literally assaulted by the smells of competing street food vendors. Within 30 steps of the gate there are 5 or 6 places to eat. If you walk down the alley in either direction that number multiplies. If you're a fan of street food you will be happy.
All in all I'm really glad I stayed there. I had had to cancel another place that simply wasn't going to work and this was a last minute booking for me, I was in the taxi on the way to it when I got the confirmation and I'm glad they had the room. If you don't need to cook and it fits your budget, you should be happy.
